Numerical Studies on Superconducting Proximity Effects and of Superconductor/Ferromagnet Spin Valve Transport Phenomena

Abstract: 
<h3 class="red">Numerical Studies on Superconducting Proximity Effects and of Superconductor/Ferromagnet Spin Valve Transport Phenomena</h3><p>These researchers are continuing and enhancing their research program in the areas of superconducting proximity effects, spin valves, and switching phenomena in superconductor-ferromagnet (S/F) heterostructures. This includes studies of the transport properties of spin valve F/F/S F/N/F/S heterostructures and Josephson S/F/N/F/S ferromagnetic junctions. The group is studying the behavior of high-quality multilayer nanostructures comprised of superconducting and ferromagnetic materials, which will be fabricated at UC Irvine. Their objective is to predict the quantitative behavior of the fabricated structures and predict the optimal configurations. They will use&nbsp; numerical methods they have developed to solve the exact microscopic equations for such systems. These methods have been shown to yield detailed agreement with experiment for equilibrium properties and the researchers are now extending them, via transfer matrix methods, to transport. Switching&nbsp; phenomena is the main focus; in particular, they will study spin valve configurations and their possible applications to energy efficient memory storage and also ferromagnetic Josephson junction structures. The computations require the parallel computing capabilities available at MSI.</p><p>Return to this PI&rsquo;s <a href="https://www.msi.umn.edu/pi/c307bd245a531c248fdd364ce50b60ae/26500">main page</a>.</p>

DMRT1 in Mammalian Sexual Development

Abstract: 
<h3 class="red">DMRT1 in Mammalian Sexual Development</h3><p>The DMRT genes are key regulators of testicular development, controlling germ cell and Sertoli cell differentiation. This group&#39;s studies in mouse models have shown that genetic deficiencies in DMRT proteins can lead to testicular dysgenesis, partial sex reversal, and testicular cancer. To pinpoint the biological processes directly controlled by DMRT genes during testis development, the reseachers use unbiased, whole-genome approaches to identify pathways that are regulated by DMRT genes and to identify interacting proteins that function with DMRT proteins to regulate testicular development. Technological advances in sequencing and proteomics have vastly increased the amount of data they collect and analyze. The computing and storage resources at MSI are essential to this research because the analysis of this data is beyond the capacities of desktop computers. This lab relies on many MSI resources to achieve their research goals and to remain competitive within this field.&nbsp;</p><p>Return to this PI&#39;s <a href="https://www.msi.umn.edu/pi/www.dmrt1.msi.umn.edu/46300">main page</a>.</p><p>&nbsp;</p>

Fetal Alcohol Spectrum Disorders Neuroimaging Research

Abstract: 
<h3 class="red">Fetal Alcohol Spectrum Disorders Neuroimaging Research</h3><p>This group is focused on uncovering the neurodevelopmental abnormalites that result from prenatal alcohol exposure. The researchers utilize structural MRI, diffusion tensor imaging (DTI), and functional MRI including resting-state functional connectivity methods. Typically, children and adolescents, ages 8 to 18, are included in these studies. The researchers collect multiple modalities of MRI data for each participant. Analyses utilize tools from the FSL library as well as in-house software. Participant numbers are currently in the range of 60 for the group&#39;s own local MRI data, but up to 500 including datasets from collaborating research sites. MSI resources are essential to this work, as they allow for parallel processing of multiple datasets and efficient throughput of data. Storage is a challenge for brain imaging data and MSI provides ample space for active datasets and ongoing temporary-space-intensive processing.</p><p>Return to this PI&#39;s <a href="https://www.msi.umn.edu/pi/fc485b46f319278a4fdd86ec0de5623b/10588">main page</a>.</p>

Orofacial Pain Neuroimaging

Abstract: 
<h3 class="red">Orofacial Pain Neuroimaging</h3><p>Chronic orofacial pain conditions presenting in the face/head (temporomandibular disorders (TMD)) or more localized to the mouth (persistent dentoalveolar pain disorder (PDAP)) cause significant societal burden. Underlying mechanisms are poorly understood with developing evidence suggesting peripheral nerve dysfunction and deficient pain modulation are involved. TMD patients were shown to have abnormal sensory/pain processing, as well as brain structural and functional differences, compared to painfree controls. Such research has yet to be explored with PDAP patients.</p><p>This project includes analysis of neuroimaging data using MSI&rsquo;s HPC resources. It uses currently available neuroimaging analysis software, e.g., FSL and Freesurfer, to process datasets. Post-processed neuroimaging datasets use significant amount of disk space, necessitating MSI&#39;s storage capabilities.</p><p>Return to this PI&#39;s <a href="https://www.msi.umn.edu/pi/68bc52332ac1be724d445b8237d0e40a/10823">main page</a>.</p>

Computational Magnetics

Abstract: 
<h3 class="red">Computational Magnetics</h3><p>This group performs calculations of magnetic properties useful for applications, particularly Spin-Torque RAM (ST-RAM) and magnetic recording. They are using MSI resources for two purposes: Finite difference time domain (FDTD) simulations of light propagation from a near field transducer, as used for heat-assisted magnetic recording (HAMR), and electronic structure calculations of magnetic damping, which is important for ST-RAM. In both cases, the researchers calculate the simple (or lower resolution cases) on their workstations, but need the resources of MSI for calculations requiring more memory. If successful, the impact of the work will be better optical designs for near field transducers and media, and lower energy ST-RAM. Both yield higher density storage/memory.</p><p>Return to this PI&#39;s <a href="https://www.msi.umn.edu/pi/171dc4bfde14e1cb4c12da3e59362c5f/37500">main page</a>.</p>
